British charity Help for Heroes is hoping to break app store records with a new game – Help for Heroes: Hero Bears – which is released for iOS and Android today.

The game costs £1.99 from Apple, Google and Amazon's app stores, with £1 from every purchase going to the charity, which supports serving and veteran members of the armed forces with serious injuries and illnesses.

Help for Heroes hopes the game will be the fastest-selling charity game on mobile devices. Developer Supersonic Software and publisher AppyNation are waiving their fees for the app, which was funded through a grant by the University of Abertay.

"The aim is simple. To raise a load of money for Help for Heroes and raise the awareness of the charity worldwide and amongst younger people," says Andy Payne from AppyNation.

The publisher is hoping to build buzz around Hero Bears today using social media tool Thunderclap, where people can sign up to post coordinated tweets, Facebook status updates and Tumblr posts at 10am today, to promote the game's release.

Hero Bears sees players controlling the Hero Bear characters as they "jump over tyres, slide under fences, leap over trenches and dodge bouncing barrels". The game also has a pair of British celebrities on board: Jeremy Clarkson and Lorraine Kelly, who appear in the game to encourage players in their efforts.
